  3. Not at all. What you're doing will lose continuity. Tutors have to explain things over on the same subject for a different person, or keep referring to a previous post. It is much more efficient for you and for tutors to refer to the same screen name.

  4. State as followings:
    P(P) = #students take physics = 32
    P(C) = #students take chemistry = 51
    P(P and C) = 15
    P(neither) = 10
    Total students = P(P) + P(C) - P(P and C) + P(neither) = 78
